vA'ICLACI-Ill/lilil1\l".l. FOR DITCH-DIGGING MACHINES.

Specification of Letters Patent.

Application led May 16, 1910. Serial No. 561,590.

To all whom 'it may concern:

4Be it known that I, WiLLiAM Aries, aV

citizen of the. United States, and a resident of Malinta, in the county of Henry andv State of Ohio,'have1 invented a certain new and useful Attachment for Ditch-Digging Machines; and I` do hereby declare the folv lowing to b'e a full, clear, and exactdescripon machinesgof this type employing a rotary excavating wheel, but is not restricted to suoli use as 1t may be employed 1n any connection for which it may be adapted or api propriate.

The object of my invention ,is the provision, in combination with a trench eX- cavating machine, of an attachment which is adapted to trail from the excavating parts at the bottom of the trench and to 'f revent the crumbs or particles of earth, 'which fall `back into the trench, from rolling tothe central portion of the trench bottom-whereby Vto interfere with the laying of tile therein, thus enabling tile to be laid with greater ease and much more rapidly than has here,

tofore been the case. 4

A further object of myl invention is the 'provision' ofl means on the lbottom of the s hoe, whichmsually trails from the excavating parts at the bottom of the trench, for forming a groove inthe central portion of the concaved trench-bottom into which any earth crumbs which may be .lying in the trenchbottomniay be brushed so as not to interfere .with the laying of tile therein.

'This 'groove also serves to maintain the tile in alinementv until the trench is refilled.

The invention'` is fully described in the following specitication,and a preferred embodiment of the same illustrated, in thetaccompanying drawings, inwhich-` Figure 1 is a side elevation of a. portion of an excavating machine, withthe 'attachment ooniprising my invention associatedl therewith. .tion of the machine and `attachmenwand Fig. 3 is a transverse section of the same and Fig. 2 is a plan view of a pora tile laid therein on the line a: in Fig.. 2.

permit tile to be deposited t erebetween on Referring to the drawings,'1 designates the usual or any suitable type of excavating.

wheel, 2 a portion of the frame-work of the machine which guides the movements of they wheel, and 3 va shoe or elongated scoop-like member, which is concavo-convex in crosssection,l and carried by apendent portion 4 of -the'fi'aine 2 in position to rest upon the central portion of/the trench bottom and to closely trail behind the wheel. This shoe `is commonly usedy in machines of this type.

The feature of my invention consists in attaching a bar 5 to each side of the rear end portion of the shoe 3 in position to trail therefrom and rest at its lower edge upon the trench bottom at the sides of the central concaved portion usually.` formedv by the .Patented Jan. 31., 1911.

wheel scoops and the shoe 3 due to the forthe trench bottom, as indicated, and are or suitable length Ato permit the placing of one or more tile lengthwise between the same to the rear of the shoeB. The inner ends of the bars 5 are preferably pivoted-to the sides of the shoe 3, as at 6, to ada t them to be swung to inoperative vertica position, as indicatedv by dotted lines in Fig. 1.

'llie bars 5 are connectedy adjacent their rear ends to the rear of their pivot by a partition member 7, which, when the bars are lowered, stands' in lverticall position and fits down closely within the shoe 3. This partition obstructs the passage of dirt 1ongitudinally through the shoe and causes'it to gather at such partition and as it rises above the' height of the shoe walls to .fall

thereover into the trench at the sides of thel shoeand bars 5, thus keeping the space be tween the bars 5 free from crumbs or the like. v

lIn practice it isfound that the laying of tile y is greatly facilitated by providing a narrow groove 8 centrally of the trench ottom longitudinally thereof, as such groove serves to aline the tile and to hold them in position until anchored by a refilling of the trench, and also lto receive lany crumbs which may happen to fall within the space -between the bars 5. To accomplish this I rio has its nose sharpened to facilitate its pas-V sagegthrough the earth.

I .wislrii nnderstood that my invention is not limited to specific construction ork arrangement of the parts, except in so far as such limitations are specified in the claims.

v Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-

f l. In a trench excavating machine, the combination `with a scoop-like shoe capable of sliding o n a trench bottom, of a pair of bars trailing from such shoe, said bars being spaced from each other and from the trench walls and a member forming a partition transversely between said bars adjacent their inner ends and fitting down within the shoe vto prevent the passage of matter there 1hrough in to the space between the memers.

In a trench excavatingmachine, -the combination with a scoop-like shoe sliding on the trench bottom, of a pair of bars .trailing from such shoe and pivoted -to the sides thereof to permit a vertical swinging of the bars, said bars being spaced from each other and from the trench walls, and aimember forming a partition transversely between said bars adjacent their pivoted ends and adapted to fit down within the shoe to prevent the passage of matter therethrough into the space between the bars.

In testimony whereof, I have hereunto signed my name to this specication in the presence of two subscribing witnesses.
